Hydrogen: A green and sustainable energy source?

Hydrogen could be a feasible alternative to fossil fuels because of its affordability and environmental friendliness. It is found throughout the environment, but producing it involves efficiently separating it from other compounds.

There are currently a number of ways this can be done, but methods can be slow and expensive. A team of scientists believes that hydrogen fuel could be generated “on-demand” because of a separation process structured around bismuth, a chemical element.
